Gregory Drozdz said it had been a "terrible nightmare" and was desperate for answers.

'Put up a fight'

He said: "Six weeks on and we're still in the dark... we've had information come to us from different sources, one official, the Foreign Office, and the unofficial, Anne-Marie's friends, but also the internet.

"We know my sister was involved in a struggle and put up a fight, but we don't know whether she was in the villa when the alleged assailant broke in, or whether she came back and found him there."
